IMPROVEMENT IN SOLE-EDGE-BURNISHING MACHINES.

Specification forming part of Letters Patent No. 131,425, dated September 17, 1872.

To all whom it may concern:

Be it known that I, AUGUSTUS G. CAREY, of Malden, in the county of Middlesex and State of Massachusetts, have invented an Improved Edge-Burnishing Machine; and I do hereby declare that the following, taken in connection with the drawing which accompanies and forms part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.

My invention relates to the organization of a machine designed for burnishing the heel and fore-part edges of boots and shoes.

In one class of such machines the shoe is mounted upon a suitable jack, which is gradually rotated to bring the entire length of edge to be burnished to the action of the burnishing-too1,and the burnisher has a constant reciprocating movement.

In my invention I impart to the burnisher a reciprocating movement; but instead of making the stroke constant or invariable for all parts of the sole-edge, I increase the length of stroke for the side edges of the sole when brought under the burnisher, making the movements short (as they have to be) when the short curves of the sole, as at the heel and toe, are in position to be burnished, and automatically lengthening the reciprocating movement as the toe or heel part passes under the path of movement of the burnisher. It is in such an organization for effecting this differential reciprocation that my invention consists.

The drawing represents a machine embodyin g the invention.

A shows the machine in side elevation. B is a plan of it. C is an end elevation.

at denotes an upright or standard, carrying at its upper end the jack-wheel b, upon which is jacked the shoe, the edge of the sole of which is to be burnished, the wheel being mounted on a pin, 0, and being turned by .hand to bring the different parts of ,the soleedge to be burnished successively to the action of the burnisher-tool. d denotes the burnisher mounted in the end of a lever, e, the front end of which lever is connected, by a link, f, with a foot-lever, g, pressure of the foot upon the lever bringing the burnisher down to the edge of the sole, and a suitable spring, h, throwing the burnisher up and out of acting position when such pressure is withdrawn. The lever e is pivoted at z to the top of a vertical lever, is, which is pivoted to a stationary fulcrum at Z. The lower arm of the lever k is connected, by a link, m, with a wristpin, 0, extending from a crank-wheel, p, on the driving-shaft q, and the rotation of the driving-shaft imparts vibratory movement to the lever 70, and thereby effects the reciprocating movement of the burnisher, as will be readily understood.

raising this'slide, the extent of vibrating movement of the lever will be increased, and by dropping it the extent of vibration will be decreased, and to produce the change of movement automatically and by the rotative movement of the shoe and in accordance with the position or part of the shoe beneath the burnisher, I connect the link at the sliding end thereof, and, by a rod, t, with one arm, u, of a lever, whose other arm, 2;, is connected, by a link, w, with an arm, 00, extending from the jack-wheel b, the arrangement of the lever mechanism being such that any movement of the jack-wheel that brings the side of the shoe directly under the burnisher raises the link m, so that the vibrations of the lever is are long, and the sweep of the burnisher correspondingly long, while any movement of the wheel that changes the position of the shoe to bring the toe or heel under the burnisher lowers the link an, and correspondingly shortens thevibrations of the lever k, and the extent of movement of the burnisher.

The arrangement of mechanism may of course be varied, the essential feature of my invention being found in a connection between the burnisher-actuating mechanism and the mechanism that rotates or positions the shoe for the action of the burnisher, so that the movement of which is automatically changed and controlled for different parts of the soleedge, substantially as described.

Executed this 5th day of July, A. D. 1872.
